Lawmakers voted to pass a bill on Tuesday authorizing conditional implementation of the July nuclear accord with major powers, IRNA reported.
The measure, whose outlines had been approved by the chamber on Sunday, secured the backing of 161 lawmakers, with 59 against and 13 abstentions.
It will now be sent to the Guardian Council for final approval before becoming law.
The deal, officially known as the Joint Comprehensive Plan of Action, reached between Iran and the P5+1 (five permanent members of the UN Security Council plus Germany), provides for the lifting of sanctions in return for time-bound limits on Tehran's nuclear program.
"The well-considered, historic decision today by legislators showed they have an accurate understanding of the country's situation," ISNA quoted government spokesman Mohammad Baqer Nobakht as saying at a press conference after the vote.
Deputy Foreign Minister for Consular, Parliamentary and Expatriates Affairs Hassan Qashqavi said, "As had been expected, the Majlis view of the JCPOA had a positive outcome. I presume it will be the same with the Guardian Council." The council is a powerful 12-member constitutionally-mandated body that vets the compatibility of all legislation with the Islamic norm and the Islamic Republic Constitution.
The latest legislation titled 'the Iranian Government's Reciprocal Action on Implementation of the JCPOA,' sponsored by the chairman of the Majlis National Security and Foreign Policy Commission Alaeddin Boroujerdi, is composed of a single article and 9 clauses.
*** Gov't Obligations
It requires the government to take into account the following considerations during the implementation of the action plan:
Current and future governments are not allowed to seek to develop and use nuclear weapons, should seriously follow the international campaign for nuclear disarmament, be actively involved in efforts to help eliminate nuclear weapons and create nuclear weapons-free zones and strive to compel Israel to abandon such weapons.
Any threat or pressure from the other side to the JCPOA would result in Iran's reconsideration of its commitment to the accord.
The government is bound to closely monitor the other side's obligations to remove sanctions and, in the event of any breach, should stop cooperation on the deal and move to increase nuclear activity back to previous levels and safeguard rights of the Iranian people.
Long-term plans aimed at commercializing the nuclear program must be pursued by the government. The 15-year plan for enrichment and research and development should be drawn up by the AEOI, after approval by the SNSC, and submitted to the UN nuclear agency in the coming months.
Redesigning the Arak heavy water reactor and, if at all, the swap of enriched uranium for natural uranium should be conducted under reliable and binding agreements.
UN inspections of Iranian facilities should be carried out within the framework of international law. Any access to the UN nuclear watchdog to military sites or relevant persons is prohibited unless separately considered and authorized by the SNSC.
Necessary measures must be taken by the government and the armed forces to boost defense capabilities and defend allies of the Islamic Republic against threats from terrorists. All organs, including the government, must act according to decisions by the SNSC to prevent abuse by foreign states, especially the US, of the conditions to emerge in the wake of the deal to gain influence in the country.
Government officials will be bound to use the overseas frozen assets to be released after financial sanctions are lifted to promote the 'resistance economy' proposed by the Leader of the Islamic Revolution, to bolster production and investment and boost the National Development Fund.
